title: Oral feeding options for people with dementia: a systematic review.
abstract: To review the benefits of oral feeding options in people with dementia.
  
  
  METHODS
  Systematic literature search with review of potentially eligible studies by two independent investigators.
  
  
  METHODS
  PubMed/MEDLINE, EMBASE, the Cochrane Library, CINAHL, and PsychINFO literature indices between January 1990 and October 2009.
  
  
  METHODS
  Clinical trials with random or nonrandom control groups were included if they reported on clinical outcomes of oral feeding interventions for people with dementia.
  
  
  METHODS
  Investigators abstracted data from included studies using a structured instrument. Studies were graded on quality and potential bias, and overall strength of evidence was summarized.
  
  
  RESULTS
  Thirteen controlled trials provided data on use of supplements for people with dementia, and 12 controlled trials tested assisted feeding or other interventions. Studies provide moderate-strength evidence for high-calorie supplements, and low-strength evidence for appetite stimulants, assisted feeding, and modified foods to promote weight gain in people with dementia. The few studies measuring function or survival showed no difference.
  
  
  CONCLUSIONS
  High-calorie supplements and other oral feeding options can help people with dementia with feeding problems to gain weight; they are unlikely to improve other outcomes. These treatments can be offered alone or in combination as an alternative to tube feeding.
